- 老旧项目 webpack 的 node-sass 依赖处理
node-sass 和 NodeJs 版本强相关，还要用 windows-build-tool 要有 python2 等依赖，在新版 NodeJs 里面已经没法使用了。但是老旧项目还想运行的话，需要使用 sass-loader 的 options 中的 implementation 属性切到 dart-sass。const webpackConfig = {//...rules: [{loader: 'sass-loader',options: { implementation: require('sass'), sourceMap: true }}]//...}
一些包装的 config 也可以用 webpack-chain 处理
// 这个参数需要根据console出来的数据结构来做，跟版本号有关系// 参考：https://github.com/XHMM/taro-plugin-dart-sass/blob/master/src/index.ts// console.log(chain.toConfig().module.rules[0])// console.log(chain.toConfig().module.rules[0].use)// console.log(chain.toConfig().module.rules[0].use[1])chain.module.rule('sass').use('1').loader('sass-loader').options({// @ts-ignoreimplementation: require('sass'),});
